Nov. 2, 2003: Variety show host Art Linkletter arrives at the "CBS At 75" celebration at the Hammerstein Ballroom in New York City.

Art Linkletter, who hosted the popular TV shows "People Are Funny" and "House Party" in the 1950s and 1960s, has died. He was 97.

His son-in-law Art Hershey says Linkletter died Wednesday at his home in the Bel-Air section of Los Angeles.

"Art Linkletter's House Party," one of television's longest-running variety shows, debuted on radio in 1944 and was seen on CBS-TV from 1952 to 1969.

Though it had many features, the best known was the daily interviews with schoolchildren.

In Memoriam

"On `House Party' I would talk to you and bring out the fact that you had been letting your boss beat you at golf over a period of months as part of your campaign to get a raise," Linkletter wrote.

"All the while, without your knowledge, your boss would be sitting a few feet away listening, and at the appropriate moment, I would bring you together," he said. "Now, that's funny, because the laugh arises out of a real situation."

Linkletter collected sayings from the children into "Kids Say The Darndest Things," and it sold in the millions. The book "70 Years of Best Sellers 1895-1965" ranked "Kids Say the Darndest Things" as the 15th top seller among nonfiction books in that period.

The primetime "People Are Funny," which began on radio in 1942 and ran on TV from 1954 to 1961, emphasized slapstick humor and audience participation _ things like throwing a pie in the face of a contestant who couldn't tell his Social Security number in five seconds, or asking him to go out and cash a check written on the side of a watermelon.

The down-to-earth charm of Linkletter's broadcast persona seemed to be mirrored by his private life with his wife of more than a half-century, Lois. They had five children, whom he wrote about in his books and called the "Links."

But in 1969, his 20-year-old daughter, Diane, jumped to her death from her sixth-floor Hollywood apartment. He blamed her death on LSD use, but toxicology tests found no LSD in her body after she died.

Still, the tragedy prompted him to become a crusader against drugs. A son, Robert, died in a car accident in 1980. Another son, Jack Linkletter, was 70 when he died of lymphoma in 2007.

Art Linkletter got his first taste of broadcasting with a part-time job while attending San Diego State College in the early 1930s. He graduated in 1934.

"I was studying to be an English professor," Linkletter once said. "But as they say, life is what happens to you while you're making other plans."

He held a series of radio and promotion jobs in California and Texas, experimenting with audience participation and remote broadcasts, before forming his own production company in the 1940s and striking it big with "People Are Funny" and "House Party."

Linkletter was born Arthur Gordon Kelly on July 17, 1912, in Moose Jaw, Saskatchewan. His unwed mother put him up for adoption when he was a baby; when he was about 7, he and his adoptive parents moved to the United States, eventually settling in San Diego.

He recalled his preacher-father forced him to take odd jobs to help the family. So Linkletter left and became a hobo, hopping trains across the West, working where he could. He recalled later that he felt the religious faith instilled by his father had been a great gift.

After leaving daily broadcasting in 1969, Linkletter continued to write, lecture and appear in television commercials.

Among his other books, were "Old Age is Not for Sissies," "How To Be a Supersalesman," "Confessions of a Happy Man," "Hobo on the Way to Heaven" and his autobiography, '`I Didn't Do It Alone."

A recording Linkletter made with his daughter Diane not long before she died, "We Love You, Call Collect," was issued after her death and won a Grammy award for best spoken word recording.

"Life is not fair ... not easy," Linkletter said in a 1990 interview by The Associated Press. "Outside, peer pressure can wreak havoc with the nicest families. So that's the part that's a gamble.

"But I'm an optimist. Even though I've had tragedies in my life, and I've seen a lot of difficult things, I still am an optimist."

Linkletter is survived by his wife, Lois, whom he married in 1935, and daughters Dawn and Sharon.
